3 MECHANICAL SET-UP
After assembly on the valve or the damper, the actuator can operate
in any position.
3.1 Opening the cover
You may need to open the cover to change the orientation of the
position indicator, or to set the cams or the positioner board.

Before its 1st use, the actuator is submitted to an IP pressure
test that tends to cause the cover seal to leave its groove.
How to open the cover
Using an 8 mm angled socket wrench, unscrew the 4 screws
fixing the cover. Do not remove them from the cover.
Upon the 1 st cover opening only: Before removing the cover,
slightly turn the cover while holding it on its housing to ensure
its seal remains in place.
Remove the cover by pulling it out along its axis.

Actuators are fitted with mechanical stops and under no
circumstances should the manual override be forced if a hard
point is detected.

However:
•
It is not recommended to install the actuator with its
cover facing downwards.
•
The cable glands must not be oriented upwards (loss
of water tightness).
